PNEUMATIC TIRE.'

leans, Louisiana, have Vinvented certain new and useful Improvements` in Pneumatica Tires, of which the following 1s a spec1ica tion. l

v My present invention relates toimprove-l ments in pneumatic or inflatable tires for vehicle wheels. y l

` Among the objects of the invention are Ito provide a tire which shall be equal in all respects in resiliency,`eiiiciency,and durability to the ordinary tire, and yet one in which the ordinary ltroubles and disadvantages due to accidental deflation are avoided.

Another object is to provide a tire which, while being a complete article and capable as such of being applied to the wheel felly, and being inflated from a single valve in the ordinary manner,is yet composed of a plurality of members or sections ,which are independent of'each other in the use of the tire upon the road to the extent that the puncturingor accidental deflation of one or more does not affect the others, the weight being sustained by the adjoining sections or members so that damage to the ydeflated. member orv members is prevented, and the tire ymay tbe used in the ordinary manner until some point is lreached where it is convement to eli'ect repalr.

Still anotherobject is tov provide means by which a member which has/been accidentally deflated may be readily-repaired, and this without removing the outer case of the section from its rim.

Other objects and advantagesv will appear from the following-specification.

The invention includes the'novel vfeatures of construction and arrangement and combination of parts hereinafter described and particularly set forth in the ap ended claims. A tire constructed in accor ance with my invention is illustrated in the accompanying drawing, in which: f

Figure 1 is a side elevation of a portion of a wheel rim with my improved tire applied thereto; Fig. 2 is a section on line 2-2 of Fig. 1'; Fig. 3 is'an enlarged detail view 'of the yvalve mechanism, being 'taken on the same section as is Fig'. 2; Fig. 4 is a longi- Speccaton of Letters Patent.

of the felly an'd circumferential tube showing the means for operating thel individual valves; Figs. 5 and .6l are 'detail views ofthe valve operating bands;'Fig. 7 is ay detail perspective 'viewgof certainfilhng' pieces 'which I find it desirable to use on heavier types of tires; and Fig. 8 is a view of the bearin surface of one of the individual tirel mem rs or sections.

Referring by reference characters to this drawing, thenumeral 1" designates the rim of the wheel which may be'applied Ito and secured upon af'ell` shownat 17 the ordinary or any. desire manner. This rim is designed to carry the individual tire members of which the number and size will `correspendL to the size of the wheel and t-he'weight to be carried thereby. The said rim 1 is provided at suitable intervals with raised circu lar bosses or projections 1a which have threaded peripheries upon which are screwed the tire cups 2. Vithin these tire cups are screwed the tire cups 3, which, in connection with the central spools 4, serve to clamp ,the lower edges of the outer cases in place. The cups 3 are formed in halves or divided, so that after 'they have been unscrewed from the main tire cups, theymay be separated to disengage them fromthe enlarged lower ends 16a of the' outer case 16. Within each outer tire case 16 is located an inner tube 15 which, as also the outer case, maybe of the ordinary or any desired construction, and each inner tube is provided with ka valve tube 14 which may .also be of the ordinary or any desired construction, and has within it a valve also of the ordinary construction and hence not shown; the valve stem of which, however, which is indicated at 13, 'is made long enou h to project beyond the tube, as indicate The valve stem is provided with a lock nut 5 screwed u'pon the threaded outerportion of the ,valve stem, which may be clamped against the flange of the spool4. i

lThe yinner ends of all of'thevvalve tubes .14 are connected by a common air tube 6,

arranged circumferentially within the recess 17* in the 'rim 17 of the wheel', an airtight connection being efected between this common air tube andtheindividual valve tubes 14 by a washer 'l'. This common air the valves.

tube 6 is provided with a sin le valvetube 24 provided with its own va ve and valve ca 24:, which cap may be removed to permit 'the attachment of an air pump by which 5 -air may be supplied to pump up all of the 'l lindividu al tire members simultaneously. In order to insure these being always pumped `or inflated to equal pressure, I provide means by which the individual valves in the valve tubes'14 may all be opened simultaneously. This means comprises two circumferentlally arranged slidin bands 9 extending each substantially hal way around the rim, which have rack sections 9aL on the ends thereof, designed to be engaged by a gear 20, fast on the shaft 21, extending radially inward throughthe felly and provided with a square end 21IL for the reception of a wrench or key by which the shaft may be turned and the bands 9 moved circumferentially. The band 9 has depressions, as clearly shown in Fig. 3, in which are seated the rounded ends of buttons, which buttons are preferably made of two sections 10 and 11, the upper section 11 having an enlarged head resting on the inside of the tube, and the inverted shank of which asses through the central opening of the disk', 12 removably threaded into the main air tube 6 and capable of bein removed when the button needs to be rep aced. The end 11 is preferabl concave, as shown, and forms a seat for t e end of the valve stem 13, and the relation of the parts is such that when the rounded ends of the buttons rest in the depressions of the bands 9, the valve stems 13 will be in such position as to allow the valves to all be closed. When, however, it is desired to open all of the valves, the rotation of the shaft 21 and gear 20 will move the bands 9 circumferentially or longitudinally in opposite directions, causing the walls of the'depressions to act as cams and force the buttons outwardly and through .pntact with the valve stems 13, unseating The projecting end of the shaft 21 is preferably provided with a removable `cover 22. The main tire cups 2 and the inner cups 3 may be provided with any convenient means for unscrewing them, as, for instance, by open` ings 19 to receive a suitable wrench, and

locking means may be provided to preventany accidental unscrewmg, as indicated by set rscrews 18. In order to further strengthen this construction for specially heavy wheels, I may provide filling blocks such as indicated at 23 and shown in detail in Fig. y7, which are designed to be placed between the adjacent cups 2, and held together by bolts.

To prevent skidding, I prefer to provide the outer faces of the tire shoes with raised portions 25 preferably of the 'shape indi- 65 cated in Fig. 8 for the purpose of giving a bet-ter gripping effect, and this also increases the resiliency of the tire.

It will be not-iced that in my construction as specifically illustrated and described, all

' parts pertaining to each particular tire member or sectlon are clrcular, and this has the effect of rendering any particular adjustment unnecessa in screwing each member into place, and rthermore, makes each section capable of being turned without producing an detrimental effect, there be.-

ing a possibi ity of such turning action in the motion of the steering wheels, for example.
